Re: xcode won't run.

First of all, back up your system.

 

Try uninstalling any Affinegy products from your user account and restarting. Test Xcode.

 

I don't see much else in your user acount, but as an aside I'd also take a look at that Silex driver. Have you updated it for Mountain Lion? If not, do so. If you don't use it anymore, remove it.

 

After updating or uninstalling anything, restart the mac and test.
